为了提高中板成品质量,开发中板新品种,争创名牌产品,邯郸钢铁总厂从提高钢水质量,根本改善板坯质量入手,一举投资1000余万元,在拥有三座5吨氧气顶吹转炉的二炼钢分厂内增设两座25吨LF精炼炉。该工程于1994年8月动工,1995年1月竣工,当月17日一次热负荷试车成功,并于2月17日投入试生产。两个月来,这两座精炼炉已处理钢水1100多炉,并取得班处理钢水29炉的好成绩。目前,这两座钢包精炼炉作业的任务尚局限于调整钢水温度、钢包底侧吹氩搅拌,以均匀钢水的温度、成分,促进夹杂上浮;下一步待风动送样装置及喂线机安装完成后,即
In order to improve the quality of finished products, the development of new varieties of plates, striving for brand-name products, Handan Iron and Steel Plant to improve the quality of molten steel to fundamentally improve the quality of slabs start with an investment of more than 1,000 yuan in possession of three 5-ton oxygen top blown converter Two steelmaking plants add two 25 tons of LF refining furnace. The project started in August 1994, completed in January 1995, a heat load on the 17th test month success, and on February 17 put into trial production. In the past two months, the two smelters have processed more than 1,100 tempering furnaces and achieved good grades in 29 tempering furnaces. At present, the tasks of the two ladle refining furnaces are still limited to adjusting the temperature of the molten steel and argon blowing on the bottom of the ladle to raise the temperature and composition of the molten steel so as to promote the inclusion floating. Next, the pneumatic feeding device and the feeder are installed When finished, that is
